摘要： A fuel vapor storage canister (10) having a screen module (52) between carbon granules (94) in the canister and a purge port (50) of the canister. The screen module (52) includes a module body (54) defining a plenum (62), a flat plastic foam screen (72) seated on an uninterrupted edge of a raised boss (60) on the module body around the plenum, and a retainer (74) clamped to the module body over the flat foam screen. A tubular stem (68) on the module body (54) plugs into a socket (36A) in the storage canister (10). An interference fit between the tubular stem (68) and the socket (36A) prevents migration of carbon granules between the socket and the tubular stem. The foam screen (72) is exposed to the carbon granules through a window in a planar side (76) of the retainer (74) which planar side, in a seated position of the retainer on the module body, cooperates with the uninterrupted edge of the raised boss (60) in compressing a segment (84) of the foam screen to define a seal around the window. Hooks (90) on the module body (54) cooperate with resilient loops (82) on the retainer (74) in maintaining the integrity of the seal around the foam screen (72) by preventing release of the retainer from its seated position on the module body.
摘要翻译：一种燃料蒸气储存罐（10），其具有在碳罐中的碳颗粒（94）和碳罐的清除端口（50）之间的筛网模块（52）。屏幕模块（52）包括限定充气室（62）的模块主体（54），位于充气室周围的模块主体上的凸起凸台（60）的不间断边缘上的扁平塑料泡沫屏（72），以及固定器（74）夹紧在平面泡沫屏上方的模块主体上。模块本体（54）上的管状杆（68）插入存储罐（10）中的插座（36A）中。管状杆（68）和插座（36A）之间的干涉配合防止碳颗粒在插座和管状杆之间迁移。泡沫筛（72）通过保持器（74）的平面侧面（76）中的窗口暴露于碳颗粒中，该平面侧在模块主体上的保持器的就座位置中与不连续的所述凸起的凸台（60）压缩所述泡沫筛的段（84）以在所述窗周围限定密封。通过防止保持器从其在其上的就座位置释放，保持模块主体54上的钩90与保持器74上的弹性环82配合以保持密封件在泡沫屏72周围的完整性。模块体。

摘要： A fuel vapor storage canister (10) including a mass of carbon granules (22) in a carbon bed chamber (20A,20B) of the canister, a liquid trap (34) having a polygonal internal chamber (44) between a vapor inlet port (48) and the carbon bed chamber, and a purge duct (66) traversing the polygonal chamber. The polygonal chamber includes a plurality of three sides (42,36B,36A) which define the gravitational bottom of the chamber in respective ones of a plurality of three orientations of the vapor storage canister. A pick-up tube (70) in the polygonal internal chamber has an outboard end (72) at the convergence of the aforesaid plurality of three sides (42,36B,36A) and an inboard end (74) surrounding an orifice (76) in the vapor purge duct. The inboard end of the pick-up tube is vertically above the maximum level of liquid fuel in the polygonal internal chamber in each of the aforesaid plurality of three orientations of the vapor storage canister. A pressure gradient between the vapor purge duct and the polygonal internal chamber induces liquid fuel to flow through the pick-up tube and the metering orifice into the vapor purge duct.

摘要： A fuel vapor storage canister (10) having a leak-proof screen assembly (64) between a mass (84) of carbon granules in the storage canister and a purge port (62) of the storage canister. The fuel vapor storage canister (10) includes a cup-shaped plastic body (12), an integral partition (16) which divides the canister body into a pair of relatively deep carbon bed chambers (18A, 18B), and a plenum (26) in the canister body at an end of one of the carbon bed chambers which is connected to the purge port (62) and which is covered by the leak-proof screen assembly (64). The leak-proof screen assembly (64) includes a plastic frame (66) ultrasonically welded to the canister body (12) and a flat fabric screen (78) having a peripheral edge (80) insert molded to the plastic frame.
